Howdy guys, so im willing to take the flaming in trade for answers to my questions. I just bought DDM 55W 5k HID's size DS2 for the Xenon housings in my e46 m3. With it being the 55w i need to get rid of the stock ballast. That's totally fine. Will it throw error codes? Also is there any cutting/drilling required to fit the bulbs into the housing? It seems that there are a lot more harnesses for the stock xenon than the two posi/neg that i came across in my old vehicle. I assume that's the power/ecu connection for the motorized projectors?

Pretty much just confusing myself. Can anyone step by step the install for me? If its simple plug and play we can leave it at that and ill slap them in once im off work today. Thanks guys
